Furniture Design Stratum Folding Chair by Ammar Kalo The Stratum chair was born out of a desire to create a chair that expresses its materiality in a very organic fashion, while taking advantage of advanced CNC milling and fabrication technologies. Comprising of two interlocking parts, the chair can fold and reduce its overall volume by half. Sharp sinuous lines run along the edges and highlight the its functional features. The flowing striated pattern is revealed by carving strategically designed local and global geometries into laminated plywood. Terminating the chair at the ground with three legs creates a sense of delicate balance.
